Monday, April 20

11:30 MATHEMATICS EDUCATION SEMINAR  - Room 447 MSC

 2:30 ANALYSIS SEMINAR  - Room 459 MSC
      Neal Carothers, Mathematics and Statistics, BGSU 
      "Riesz Bases III"
      Abstract: The continuing saga of unconditional bases in Hilbert
        space.
                
 3:30 LUKACS LECTURE  - Room 459 MSC
      C. R. Rao, Distinguished Lukacs Professor, BGSU
      "Pre- and Post-Least-Squares: The Emergence of Robust Estimation" 
      Abstract: From the time of Ptolemy, astronomers were faced with
        the problem of obtaining best estimates of unknown parameters
        from measurements subject to error.  Various attempts, partly
        objective and partly subjective were made during the last five
        centuries, which finally led to the discovery of the method of
        least squares (LSE) in the beginning of the last century in
        which Gauss (1777-1855) and Laplace (1749-1827) played major
        roles.  Subsequent contributions by Markoff, Aitken, Bose, and
        Rao provided generalizations of LSE to cover a number of
        practical situations.  A historical account of the development
        of LSE will be presented.

        LSE has nice properties when errors are normally distributed.
        However, they are sensitive to departures from normality and
        the presence of outliers.  Some of the latest methods in what
        is called M-estimation, which are robust to model deviations
        and outliers will be discussed.

      *** Note change of time ***
      Tom Hinrichs, Mathematics and Statistics, BGSU 
      "The Theory of Equations in the Eighteenth Century"
      As always, all are welcome to attend. 
      Abstract: An eighteenth century look at the theory of equations
        and its relation to the Fundamental Theory of Algebra
        (FTA). This is a quick review of the evolution of the FTA from
        Leibniz to Lagrange.
